If it's a copper connection, you could connect a PC instead of the OSA and see if it connects to the switch. For all connections there are devices that will tell you if the cable is connected.

This is for new Lpar (not yet IPLed) and new OSA card. Switch side connection shows no signal due to no TCPIP at Lpar side. Is there any way to verify physical connection, without IPLing the Lpar?
